Which statement best describes the arm symptoms described in Souza's discussion of TOS?

In thoracic outlet syndrome, the arm symptoms are typically diffuse rather than confined to a single small area. This happens because compression at the thoracic outlet can affect multiple nerve fibers within the brachial plexus (often the lower trunk, C8–T1) and can involve vascular structures as well. The result is a broad, widespread mix of sensory changes, pain, and sometimes weakness that can involve the shoulder, arm, forearm, and hand rather than a narrowly localized spot. While vascular symptoms can occur, they aren’t the sole or most consistent feature, and some neurogenic symptoms are usually present. So describing the arm symptoms as diffuse best matches Souza’s discussion of TOS.
